If you own an Epson EcoTank / L-Series printer (such as the L3100~L3168, L1110, L5190, ET-2710, ET-4700), after printing a certain threshold of pages, printing will suddenly halt with the Power light and Ink/Paper warning lights flashing alternately.

Depending on your driver version and OS, EPSON Status Monitor 3 will throw one of these exact verbatim warning messages:

Message 1 (Final Service Lockout - Most Common):
“A printer’s ink pad is at the end of its service life. Please contact Epson Support.”
(Or: “The printer’s ink pads are at the end of their service life.”)

Message 2 (Pre-lockout Warning):
“A printer’s ink pad is nearing the end of its service life. Please contact Epson Support.”

Message 3 (Status Code on LCD / Utility):
Error Code: E-11 (Ink pad life expired / Service required)

If you found this page by searching the exact prompt “A printer’s ink pad is at the end of its service life”, this guide solves your issue without paying for service centers or scammy reset utilities.

When searching for solutions online, users typically hit two frustrating roadblocks:

1. Expensive and scammy software resets: Tools like WIC Reset require you to buy a one-time reset key for $10–$15. Free alternatives like the Epson Adjustment Program (AdjProg) are 99% Windows-only .exe binaries, often flagged by antiviruses and unusable on macOS (MacBook) or Linux.
2. Overpriced plastic assembly: Buying the entire plastic cartridge housing costs significantly more and creates unnecessary plastic waste, even though the plastic case itself is completely intact and reusable.

By replacing only the felt absorption pads and using an open-source Python tool (reinkpy-fix) with an AI coding assistant or terminal, you can completely repair your printer in under 10 minutes for roughly $4–$5 on any operating system.

1. Cost & Waste Comparison: Full Assembly vs. Felt Pads Only

The waste ink maintenance box is just a molded plastic container. What actually gets saturated with discarded ink is the felt absorption pads inside.

You only need to buy pre-cut replacement sponge pads for your model (e.g. L3100 / L3110 / L3150) from online marketplaces like Amazon, AliExpress, or local vendors.

2. Hardware Replacement (Takes 5 Minutes)

Items needed: Cross-head screwdriver, disposable gloves (or tweezers), paper towels, new felt pads.

1. Power Off: Disconnect the power cord and USB cable.
2. Remove Outer Screw: Locate the single screw on the lower right back panel of the printer. Unscrew it and slide the small plastic cover downwards to remove it.
3. Slide Out Ink Box: Remove the inner screw securing the waste ink container. Slide the container out gently towards the right.
4. Swap Sponges: Wearing gloves, pull out the ink-soaked sponges and discard them into a trash bag. Wipe the inside of the plastic casing with a paper towel, then insert the new, clean felt pads in the exact same orientation.
5. Reassemble: Slide the box back into the printer, tighten both screws, and reattach the cover.

3. Software Counter Reset via reinkpy-fix (Cross-Platform)

Physical pad replacement is only half the battle. The internal EEPROM memory in the printer still retains the maximum counter value, which must be reset to 0%.

Instead of paying for proprietary reset keys or hunting down sketchy Windows-only tools, we use reinkpy-fix, an open-source Python tool that communicates directly with the printer over low-level USB commands.

You can run the steps manually in your terminal, or pass the copy-paste prompt below directly to an AI coding assistant (such as Claude Code, Cursor, Codex, or Antigravity) to automate environment setup, bug patching, device detection, and EEPROM resetting in under 2 minutes.

💡 Ready-to-use AI Agent Prompt (Copy & Paste)

Copy the prompt block below and paste it directly into your AI coding assistant:

My Epson printer (model: L3106 / L3100 or ET-2710 series) is locked due to "waste ink pad at the end of its service life".
It is connected via USB to my macOS/Linux machine. Please automate the 0% counter reset following these exact steps:

1. Clone repository: https://github.com/LeFZdev/reinkpy-fix
2. Ensure libusb is installed (e.g. run 'brew install libusb' on macOS or 'apt-get install libusb-1.0-0-dev' on Linux).
3. Set up a virtualenv (python3 -m venv venv) and install dependencies:
   venv/bin/pip install pyusb pysnmp zeroconf
   venv/bin/pip install -e .
4. (CRITICAL BUG FIX) In reinkpy/__init__.py, find two occurrences of 'from usb import UsbIO' and replace them with 'from .usbtest import UsbIO'.
5. Replace reinkpy/main.py with this reset routine:
```python
import reinkpy
printer = reinkpy.Device.from_usb(manufacturer='EPSON')
driver = printer.epson
if not driver.spec.model:
    driver.configure("L3106")  # adjust to your model e.g. L3150, ET-2710
print("Connected Printer:", printer)
print("Configured Model:", driver.spec.model)
driver.reset_waste()
print("Waste ink pad counter successfully reset to 0%!")

1. Execute with elevated permissions: sudo venv/bin/python3 reinkpy/main.py and verify reset completion. ```

🛠 Step-by-Step Manual Terminal Guide

If you prefer executing the commands manually without an AI assistant:

Step 1 — Clone the Repository

Clone the patched repository locally:

git clone https://github.com/LeFZdev/reinkpy-fix
cd reinkpy-fix

Step 2 — Install libusb

libusb is required for raw USB device communication on macOS and Linux.

On macOS (via Homebrew):

brew install libusb

On Ubuntu/Debian Linux:

sudo apt-get install libusb-1.0-0-dev

Step 3 — Create Virtual Environment & Install Dependencies

python3 -m venv venv
venv/bin/pip install pyusb pysnmp zeroconf
venv/bin/pip install -e .

Step 4 — Fix Library Import Bug (Crucial Step!)

In the current reinkpy-fix repository commit, running the script immediately results in an ImportError. The underlying file usb.py was renamed to usbtest.py, but reinkpy/__init__.py was not updated.

Open reinkpy/__init__.py and search for from usb import UsbIO. You will find two occurrences. Change both lines to:

# Before
from usb import UsbIO

# After
from .usbtest import UsbIO

(If you are using an AI coding agent, simply tell it: “Fix the UsbIO import in reinkpy/init.py to import from .usbtest”, and it will patch the file instantly.)

Step 5 — Replace main.py with USB Reset Routine

Replace the entire contents of reinkpy/main.py with the following clean reset script:

import reinkpy

# Discover connected EPSON USB printer
printer = reinkpy.Device.from_usb(manufacturer='EPSON')

driver = printer.epson
if not driver.spec.model:
    driver.configure("L3106")  # Specify your model or compatible series (e.g. L3100, L3106, L3150)

print("Connected Printer:", printer)
print("Configured Model:", driver.spec.model)

# Reset waste ink counter to 0%
driver.reset_waste()
print("Waste ink pad counter successfully reset to 0%!")

Step 6 — Execute with Elevated Privileges

Raw USB access requires root permissions on macOS/Linux:

sudo venv/bin/python3 reinkpy/main.py

You will see output identifying your printer followed by:

Connected Printer: <Device EPSON ...>
Configured Model: L3106
Waste ink pad counter successfully reset to 0%!

Finally, turn the printer off and back on. The flashing warning lights will disappear, and the printer will return to a completely normal and ready printing state!

Supported Epson Printer Models (Asia L-Series & Global EcoTank)

The reinkpy-fix reset procedure applies 100% identically across all models sharing the same internal motherboard and USB communication protocol:

1) Asian / Domestic Models (L-Series — 33 Models)

• L3100 Models: L3100, L3101, L3104, L3105, L3106, L3107, L3108, L3109
• L3110 Models: L3110, L3111, L3114, L3115, L3116, L3117, L3118, L3119
• L3150 Models (Wi-Fi): L3150, L3151, L3152, L3153, L3156, L3158
• L3160 Models (with LCD): L3160, L3161, L3163, L3165, L3166, L3168
• L1110 Models (Single-function): L1110, L1118, L1119
• L5190 Models (Fax / ADF): L5190, L5196, L5198

2) North American & European Models (EcoTank / ET Series)

Global EcoTank models share the exact same firmware / EEPROM architecture:

• ET-1110 ~ ET-1118 (Global equivalent of L1110)
• ET-2710 ~ ET-2728 (Global equivalent of L3110 / L3150)
• ET-4700 (Global equivalent of L5190 Fax All-in-One)

Configuration Note: In Step 5, simply replace driver.configure("L3106") in main.py with your exact model string (e.g., L3150, L1110, L5190, ET-2710). The driver will target the exact memory register of your printer.

Important: Physical Disassembly Nuances by Model

While the software reset is identical across all models listed above, the physical teardown process varies slightly by form factor:

• L3100 ~ L3119 (including L3106): Same generation and identical chassis. The 1-screw lower-right rear panel and slide-out box mechanism described in Step 2 is 100% identical.
• L3150 / L3160 Series: Includes Wi-Fi modules and LCD screens, but the rear lower chassis and waste pad box placement remain virtually the same.
• L1110 Series (Compact Single-function) / L5190 Series (ADF / Fax): Different physical form factors. Screw locations and exterior casing latches may vary, so double-check your model’s specific service casing layout before pulling the box out.

Summary: Solved in 10 Minutes with $5

• Total Cost: ~$5 for felt pads (Zero dollars spent on reset keys)
• Time Spent: 5 mins physical pad swap + 5 mins terminal reset = 10 minutes total
• Key Advantage: 100% native on macOS and Linux without Windows virtualization, and reusable for every future reset cycle.
